Embodiment Construction

[0220] according to figure 1 The smoking article 2 of the first embodiment of the invention shown in , comprises a combustible carbonaceous heat source 4 having a front face 6 and an opposed rear end face 8, an aerosol-forming substrate 10, a transfer element 12, an aerosol cooling element 14, a spacer The element 16 is coaxially aligned with the adjoining mouthpiece 18 . Such as figure 1 As shown, the aerosol-forming substrate 10, delivery element 12, aerosol cooling element 14, spacer element 16, and mouthpiece 18 and the rear of the plugged combustible heat source 4 are wrapped in an outer wrapping material 20 of sheet material, such as cigarette paper. .

[0221] The combustible carbonaceous heat source 4 is a plugged combustible carbonaceous heat source and is located at the distal end of the smoking article 2 . Such as figure 1 As shown, a substantially air-tight non-combustible barrier 22 in the form of a disc of aluminum foil is provided between the rear end face 8...

Abstract

A smoking article (2) comprises: a combustible carbonaceous heat source (4) having opposed front and rear end faces (6, 8); an aerosol-forming substrate (10) downstream of the rear end face (8) of the combustible carbonaceous heat source; an ignitable composition (38) provided on at least a portion of the front end face (6) of the combustible carbonaceous heat source (4); and one or more airflow pathways along which air may be drawn through the smoking article for inhalation by a user. The ignitable composition (38) is capable of being ignited by striking the front end face (6) of the combustible carbonaceous heat source (4) on a frictional surface. The ignitable composition (38) is isolated from the one or more airflow pathways such that, in use, air drawn along the one or more airflow pathways does not directly contact the ignitable composition (38).

Description

technical field [0001] The present invention relates to a smoking article comprising a friction ignition combustible carbonaceous heat source. Background technique [0002] Various smoking articles in which tobacco is heated rather than combusted have been proposed in the art. One object of such 'heated' smoking articles is to reduce known types of noxious smoke constituents produced by combustion and pyrolytic degradation of the tobacco in conventional cigarettes. In one known type of heated smoking article, the aerosol is generated by transferring heat generated by a combustible carbonaceous heat source to an aerosol-forming substrate located downstream of the combustible carbonaceous heat source. During smoking, the aerosol-forming substrate releases volatile compounds by heat transferred from the combustible carbonaceous heat source and the volatile compounds are entrained in the air drawn through the smoking article. As the released compound cools, the compound conden...
